Modern SEO is not hard. It is massive.
You are expected to update thousands of links, fix anchor texts across entire sections of your site, and publish article after article at a pace no human team can sustain. You cannot do that with spreadsheets or outdated tools. And every week where your content sits still is a week where your competitors move ahead.
Deadlines slip. Backlogs grow. Rankings stall.
Your internal mesh quietly decays and the work that actually matters never gets done in time.
